Out of the 912 HCPs who were surveyed, 556 of them are considered loyal HCPs and 356 are Splitter HCPs. **Among the loyal HCPs, the majority (56.8%) exclusively administer PCV15** to their eligible patients. However, a significant portion (42.6%) of Loyal HCPs exclusively administer PCV13, indicating a relatively close gap between the two brands.
To further understand the preferences of the Splitter HCPs, we defined "predominant users" as those who use a specific brand at least 70% of the time. Among the Splitter HCPs, predominant users of PCV13 has a strong foothold, accounting for 32.9% of the splitters. In contrast, PCV15 is only utilized by a small proportion (5.6%) of the splitter HCPs. Another potential opportunity for growth may lie among the undecided group, which includes the 218 splitter HCPs who have not reached the 70% usage threshold for any brand.
At the patient level, the usage of PCV13 and PCV15 is relatively similar (53.0% vs. 46.3%). However, when focusing on the patients who received PCV15, the majority (63.5%) of them (1361 out of 2143) came from the patient pool of loyal HCPs -- suggesting that the **usage of PCV15 among patients is primarily driven by Loyal HCPs**. This is in contrast with the pattern observed for PCV13-administered patients, where distribution of PCV13 patients does not show a clear majority from either Loyal or Splitter HCPs.
To better understand the differences between Loyal HCPs and splitter HCPs, we examined their vaccinating behavior within their eligible patient pool. The figure above illustrates that, on average, a Splitter HCP sees 10 eligible patients per week, while a loyal HCP sees fewer patients, around 6 per week. However, despite having a smaller patient pool, Loyal HCPs exhibit a lower fallout rate at 33.3% vs. as high as 50% among the Splitter HCPs. This finding suggests that Loyal HCPs may be more proactive in administering pneumococcal vaccines, particularly PCV, to their eligible patients.
The figures below represent the responses of Loyal HCPs who exclusively administer PCV15, highlighting the reasons that could reinforce their loyalty towards our brand.
The figures below represent the responses of Splitter HCPs who predominantly administer PCV15, highlighting the reasons that could nudge them towards fully shifting to our brand.
The figures below represent the responses of Splitter HCPs who remain undecided, highlighting the reasons that could influence them towards administering PCV15 more often.
